[amp_mcq option1=”-1″ option2=”#NAME?” option3=”#NAME?” option4=”-R E. None of the above” correct=”option4″]
The correct answer is: D. -R
The -R option is used with the chmod command to apply the specified permissions recursively to all files and sub-directories in a directory.
The -1 option is used to set the permissions of a file to 1, which means that the file can only be read by the owner.
The #NAME? option is used to specify a file name pattern.
The #NAME? option is not a valid option for the chmod command.
Here is an example of how to use the chmod command with the -R option:
chmod -R a+rwx /path/to/directory
This command will set the permissions of all files and sub-directories in the directory /path/to/directory to allow all users to read, write, and execute the files.
